Which narrative "mistake" was bigger

[TMC]

• Putting Cory, Shawn, and Topanga in high school after sixth grade, because it boxed them in by having them in high school for six years.

or

• Mysteriously skipping two years in order to get them out of high school in four years, i.e. bailing themselves out of their first mistake.

With that, do you think or agree with the notion that Boy Meets World should have ended with their high school graduation, after which they go out into the world?
